Subject: [PATCH 2/2] Low: libcrmcommon: Allow negative numbers as cmdline
options.
The bug here is that negative numbers (for instance, negative scores)
are not supported as command line arguments. Because we break up a
string that starts with a single dash into multiple arguments, "-1000"
becomes "-1", "-0", "-0", and "-0".
Because we don't have enough information about what is happening on the
command line, the best we can do here is recognize something as a
negative number and pass it on. Any errors will have to be detected at
a later step.
Also note that we only recognize negative numbers if they start with
1-9. Starting with 0 will be recognized as some sort of string.
Regression in 2.1.0 caused by a long-standing bug in
pcmk__cmdline_preproc_test.
