[PATCH] builtin/apply.c: use iswspace() to detect line-ending-like chars

[George Papanikolaou <g3orge.app@gmail.com>]

Removing the bloat of checking for both '\r' and '\n' with the prettier
iswspace() function which checks for other characters as well. (read: \f \t \v)
---

This is one more try to clean up this fuzzy_matchlines() function as part of a
microproject for GSOC. The rest more clarrified microprojects were taken.
I'm obviously planning on applying.

Thanks
