[PATCH] tail: adjust type of a local variable

[Jim Meyering]

I noticed new warnings:

    tail.c: In function ‘tail_forever_inotify’:
    tail.c:1256: warning: comparison between signed and unsigned
    tail.c:1263: warning: comparison between signed and unsigned
    tail.c:1272: warning: comparison between signed and unsigned

and fixed it like this:

Subject: [PATCH] tail: adjust type of a local variable

* src/tail.c (tail_forever_inotify): Declare "len" to be of type
size_t, not ssize_t, since the former is what safe_read returns.
