Why do you think so?

`ffap-string-at-point':
Return a string of characters from around point.

`comint-extract-string':
Return string around point, or nil.

My library thingatpt+.el defines these, based
loosely on `comint-extract-string':

`string-at-point'
`string-nearest-point'
`string-contents-at-point'
`string-contents-nearest-point'

The last two are the same as the first two,
except they don't include the string delimiters.
