--- Comment #1 from Yuri Pankov <yur...@yuripv.net> ---
There are several problems here:
- by default, regcomp() is called with REG_EXTENDED, so '+' is a special
character and needs to be escaped
- once you quote '+', it becomes ordinary, but '+' is NOT a word character, so
matching fails
`whatis c+` (single plus) returns the same results as `whatis c`, as '+' means
"match 1 or more occurrences".
whatis could be changed to use REG_BASIC instead of REG_EXTENDED, but still,
"c++" is not a word, and won't match.
Given the above, this isn't really a bug as man page says "words" and not
"exact strings" :-)
