I wonder how I can handle the line continuation character of groff in
font-lock. Contrary to other languages, a trailing `\' is handled on
the input level, before anything else. For example
This is a \
.test
is equal to
This is a .test
Similarly,
.foo "This is a \
test"
Is equal to
.foo "This is a test"
Consequently, for proper fontification, I have to handle trailing
backslashes earlier than anything else, too. Looking into the
documentation I wasn't able to find a method to do that. The nearest
thing I can find is font-lock-syntactic keywords, but I have the
feeling that this a)comes too late and b)is not appropriate, since
backslashes are not limited to any synctical element.
A possible solution might be to call a function which assigns a
special text property to the newline character if preceded by `\'
(basically an `ignore me' or `neutral' category) while doing
fontification. Unfortunately, regular expressions don't have access
to text properties...
Any ideas?
