[patch] Fix *.log tests merged output containing "==="

[Jan Kratochvil <jan.kratochvil@redhat.com>]

Hi,

while *.sum files were OK the *.log files sometimes miss the content present
in *.sum results.  For example gdb.base/bitfields.exp output was missing while
gdb.base/bitfields.exp output was present.

It got broken if arbitrary "===" string has appeared in the tests output.

Grepped dejagnu the proposed more strict pattern should match fine:

$ grep === `rpm -ql dejagnu`
/usr/share/dejagnu/framework.exp:	clone_output "\n\t\t=== $tool Summary for $current_target_name ===\n"
/usr/share/dejagnu/framework.exp:	clone_output "\n\t\t=== $tool Summary ===\n"
/usr/share/dejagnu/runtest.exp:clone_output "\n\t\t=== $tool tests ===\n"

For GDB `grep '^Running ' gdb.log | wc -l' changes 1770 -> 1818.
For GCC `cat *.log | wc -l' changes 444633 -> 482178.
(checked the output change looks OK for both cases)

I am not aware why there was "/\===/" instead of just "/===/".

OK to check-in?  (GCC + GDB approval requested)


Thanks,
Jan
