PATCH: contrib/repro_fail: filter out "-ignore SIGHUP" from spawn line

[David Malcolm <dmalcolm at redhat dot com>]

I'm attempting to use contrib/repro_fail to track down my testcase
failures, but the spawn lines of the testcases I'm interested are of the
form:

  spawn -ignore SIGHUP COMMAND ARGS

rather than just:

  spawn COMMAND ARGS

which leads to repro_fail's attempt to rerun the command failing with:

../src/contrib/repro_fail: line 92: -ignore: command not found

I'm attaching a patch which filters away such "-ignore SIGHUP"
directives from the spawn lines so that it can rerun the failing tests.

Seems to work, but this is the first time I've run repro_fail


Hope this is helpful
Dave
