Subject: Fix emission of string initializers.
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=7491bedf6b9fb310379481c7cd10521d60ea6c46;p=libfirm

Fix emission of string initializers.

Non-printable characters are emitted as octal sequences, e.g. \0 for 0.
Always pad them to three digits, so they do not accidently join with a following ASCII digit.
E.g. "\0""7" was emitted as "\07", correct is "\0007".
