#1500 Bash: Fix quoted HereDoc delimiters handling

[Colomban Wendling]

Bash quoted HereDoc delimiters seem to allow pretty much anything as part of the delimiter, not only identifiers. E.g. the following snippet is valid:

cat << EOF
line1
line2
EOF

echo "ouside"

cat << '\A \\B \'
line1
line2
\A \\B \

echo "ouside"

cat << "\A \\B \"C"
line1
line2
\A \B "C

echo "ouside"

Currently the Bash lexer doesn't handle quoted delimiter differently from non-quoted ones apart from the quotes themselves, which leads to broken highlighting if a quoted delimiter contains anything but an identifier.

Attached is a patch fixing the issue by properly handling the quoted delimiters.

I'm occupied with other things at the moment; looks fine by me. Perl coders seem to be amazingly good at hitting corner cases... :-p

Haha, I don't do Perl, I'm just maintaining Geany, thus get a ton of annoying bug reports like https://sourceforge.net/p/geany/bugs/952/ ;)
