[-- Attachment #1: Type: text/plain, Size: 252 bytes --]

The only two changes which aren't obvious are s/dirified/specified/ and
s/edirially/especially/ which appear to be caused by a s/spec/dir/ edit
that went too far.

gcc/ChangeLog:

	* gimple-ssa-sprintf.c: Fix typos in comments.

Committed as obvious.
