Implement a radical approach to improving abilities of plugins to detect
and handle various changes of micro's state: add onAnyEvent callback
which is called, literally, after any event. A plugin can use this
callback to compare a state after the previous event and after the
current event, and thus is able to catch various events that cannot be
detected using other callbacks.
Some examples of such events:
- change of current working directory
- switching cursor focus between a bufpane and the command bar
- change of message text in the status bar
* parser: Precise error message for missing `start` & `end` in region
* parser: Check and prompt for empty patterns and region properties
* syntax: Remove empty identifier pattern from log definition
Support crontab filetype detection in the case crontab is opened via
sudoedit. Also apparently this fixes crontab filetype detection when
it is opened normally via `crontab -e` but in MacOS.
Fixes#3172
This typo causes a funny bug: the autodetected filetype for *.jsonnet
files is an empty string instead of "jsonnet".
Even funnier, when autocompleting "set filetype " (with the fix from
PR #3218), the first suggested filetype is this empty string.
The section says that users may use their own .hdr files for their own
custom syntax files, which is simply not true.
As a matter of fact, .hdr files are an implementation detail that
doesn't need to be mentioned in the user documentation.
Turning `header` patterns into `signature` patterns in all syntax files
was a mistake. The two are different things. In almost all syntax files
those patterns are things like shebangs or <?xml ... ?> or
<!DOCTYPE html5> i.e. things that:
1. can be (and should be) used for detecting the filetype when there is
no `filename` match (and that is actually the purpose of those
patterns, so it's a regression that it doesn't work anymore).
2. should only occur in the first line of the file, not in the first
100 lines or so.
In other words, the old `header` semantics was exactly what was needed
for those filetypes, while the new `signature` semantics makes little
sense for them.
So replace `signature` back with `header` in most syntax files. Keep
`signature` only in C++ and Objective-C syntax files, for which it was
actually introduced.
Replacing header patterns with signature patterns was a mistake, since
both have their own uses. So restore support for header regex, while
keeping support for signature regex as well.

Directly using Go's time.AfterFunc() from lua is tricky. First, it
requires the lua timer callback to explicitly lock ulua.Lock to prevent
races. Second, it requires the lua timer callback to explicitly redraw
the screen if the callback changes the screen contents (see #2923).
So instead provide micro's own timer API which ensures both
synchronization and redrawing on its own, instead of leaving this burden
to lua code. In fact, its implementation runs the lua timer callback in
the main micro's goroutine (i.e. from micro's perspective it is
synchronous, not asynchronous), so both redrawing and synchronization
are ensured automatically.
Fixes#2923
* Update commands.md
removed question marks since they're not meant to be typed and their meaning is equivocal
* Update commands.md
added brackets around optional arguments, and added 'key' placeholder indicating a required argument for 'showkey'
* Update commands.md
added single quotes inside of bracketed optional params (though I feel they should be reserved for shell escaping, and italics should be used for replacing text of arguments. I also added brackets (and quotes) around the `exec` parameter for `term`, although I'm not really sure if that's right because this command doesn't work on my system.
