action/command: Allow `-vsplit` & `-hsplit` as optional argument for `help`
Additionally the help, vsplit and hsplit command can now open multiple files like the tab command.
When saving a file with sudo fails (e.g. if we set `sucmd` to a
non-existent binary, e.g. `set sucmd aaa`), we erroneously return
success instead of the error, as a result we report to the user that
that the file has been successfully saved. Fix it.
When we are saving a file with sudo, if we interrupt sudo via Ctrl-c,
it doesn't just kill sudo, it kills micro itself.
The cause is the same as in the issue #2612 for RunInteractiveShell()
which was fixed by #3357. So fix it the same way as in #3357.
When adding a new `BufPane` it is always being inserted last into `MainTab().Panes`.
This leads to a confusion when using the actions `PreviousSplit`, `NextSplit` as the previous/next split may not be the expected one.
How to reproduce:
- Launch micro and insert char "1"
- Open a new vsplit via the command `vsplit` and insert "2"
- Switch back to the left split (1) by using `PreviousSplit`
- Again open a new vsplit via command: `vsplit` and type char "3"
- Now switch between the 3 splits using `PreviousSplit`, `NextSplit`
Switching from most left split to the most right, the expected order would be 1, 3, 2 but actually is 1, 2, 3.
When we temporarily disable the screen (e.g. during RunInteractiveShell)
and then enable it again, we reinitialize tcell.Screen from scratch, so
we need to register all previously registered raw escape sequences once
again. Otherwise raw escape bindings stop working, since the list of
raw escape sequences of this newly create tcell.Screen is empty.
Fixes#3392
In rust, there are some prefixes that may be part of the string literal.
String literals of the form b"test" (and br##"test"## etc) are byte
strings (as opposed to unicode strings), and similarly, string literals
of the form c"test" are C zero-terminated strings. Hence, added optional
prefixes to each of the string regular expressions so the prefix will be
recognized as part of the string.
Built and tested after fix.

Update from PR feedback:
Coalesce multiple statement rules into one.
Coalesce multiple constant.number into one.
Update from more PR feedback:
Fix special variables (starting with $)--var must start with $,
i.e. x$y is not a valid special var, but you can have x=$y.
Compiled and tested again with latest changes.
