Sounds like a bug in reporting matches.  We invoke lid with the -w
switch, which should have reported only complete symbols, AFAIU
(although the documentation confusingly talks about "words").  Perhaps
report this to the developers.

Anyway, if you search in the hits instead of in the file's buffer,
this problem should not affect us, I think.
