Finding the current function now better handles the case the current
line is after a function but outside its scope, and many other issues
the scope reporting had.
The code assumed that if both old and new fold levels were above the
minimal function fold level the function couldn't have been changed,
which is wrong if a function can appear both inside and outside another
fold level (e.g. inside or outside a class).
This makes symbols_get_current_function() more accurate by using TM
data even on a modified file if realtime tag parsing is enabled, thus
if the data has reasonable chances to be correct.
This prevents a crash if the VTE library we happen to load lacks a
symbol we need, which can happen e.g. if the user passed an improper
library to the --vte-lib command-line option or if the VTE library is
loadable but broken.
When clicking a symbol in the Symbols sidebar and holding the Control modifier key, don't
set the focus to the editor widget so further navigation in the Symbols sidebar with keys
is possible.
When collapsing a fold range whose starting line is offscreen,
scroll the starting line to display at the top of the view.
Otherwise it can be confusing when the document scrolls down to hide
the folded lines.
Since reading locale and reading encodings from within files by regex
can find encodings not on the Geany list, saving as text ensures that
any encoding found can be saved in the session, otherwise a file can
be opened but will not re-open because the encoding cannot be saved
in the session. Since numeric encoding names exist prefix the text
name by 'E' so they can be distinguished from saved numeric indexes.
This ungetc() call don't look legitimate and actually leads to lots
of warnings about ungetc() being called when another character was
already backed up.
This removes tags like 'pass_', 'pass_stmt' or 'return_stmt' which are quite annoying
when typing the actual keywords and pressing Enter afterwards.
Also add some more modules and packages to the ignore list to avoid weird side effects
when importing them (even though antigravity is funny).
