ginsbach 094918e495 The sign is optional in an exponent 
Treat numbers after [Ee] as a positive number rather than an invalid
numeric sequence.  (Taken from FreeBSD but done differently.)

christos 5a1e6eb35b document non literal string format 2011-08-17 13:19:09 +00:00
dholland d6986f611b Rerun valid_format() both before and after unescaping the format 
string, in case the format string contains printf conversions
assembled from escape sequences.

A better approach might be to adjust the unescape logic to avoid
generating printf conversions (e.g. convert \x25 to %% instead of %)
but that's somewhat problematic and it's not really worth taking the
trouble.

Running valid_format() only after unescaping would also be somewhat
tidier but makes printing the invalid format string problematic,
because the unescape logic runs in place.

None of these cases are really worth worrying about in detail, but now
at least they don't result in SIGSEGV.

Related to PR 43355.

dholland 76c7c8ecbf Fix valid_format() to be more careful about allowing only valid printf 
formats.

Also, accept %a and %A, which are new since this logic was last updated,
and also allow %F even though it's not functionally different from %f.
Document these additions and bump date of man page.

Fixes PR 43355.

was not copied to the output.
