a) That increases the parsing time. Like, makes in 2-3 times longer in
one example I had.
b) It creates very weird entries, like some multiline undisplayable byte
sequence in one example (an OTF file, IIRC), and those do show up in the
completions list, for xref-find-references. Or C-u xref-find-definitions.
c) It does create false positives for real names. For instance, I can
search for the definition of 'push' (a method in Ruby or JS), and it
will show me these as possible destinations:
/home/dgutov/xxx/yyy/zzz/public/app/less/bs-less/mixins/grid.less
33: .make-xs-column-push(
57: .make-sm-column-push(
85: .make-md-column-push(
113: .make-lg-column-push(
