emacs mode: match keywords on the start/end of symbols

If keywords are matched on the start/end of words then
keywords are also matched if they are surrounded by dashes
or underscores. For example the keyword with is highlighted
in geany-with-vte. When matching on the start/end of symbols
the keyword is only highlighted if it is not part of an other
identifier.
