I think you picked a bad example ;-). From just the line you commented on, I would \
have said that a '!' looked reasonable in this case, and felt inspired to come toss \
my 2 ¢ in. Then I looked at the rest of the diff, and have to agree, the others \
are... more unexpected :-).
(p.s. Are you intending to open issues? If not - and considering you also said 'ship \
it!' I would guesss 'not' is the case - you may want to uncheck that option in your \
user preferences...)

endRegion attributes are not processed. Therefore, a rule like the following does not \
work: <StringDetect String="x" lookAhead="true" \
endRegion="a" beginRegion="a" />
This patch fixes this. Therefore, using endRegion and beginRegion along with \
lookAhead will
- not process any characters as before, but
- folding regions are still processed.
This effectively means, that TextLineData::addAttribute (const Attribute \
&attribute) is called as follows: one time for endRegion:
Attribute(offset, length=0, someAttribute (does not matter, since length=0), \
someFoldingId) one time for startRegion:
Attribute(offset, length=0, someAttribute (does not matter, since length=0), \
someFoldingId)
The endRegion is pushed first, i.e. before the startRegion.
The changes are as follows:
1. The folding stuff is moved out of the if (!lookAhead) {...} scope, and therefore \
always executed 2. Therewith, the if (!lookAhead) {...} scope is split into two \
scopes. The first one is moved a bit up.</pre> </td>
