[Message part 3 (text/plain, inline)]

The 'sort' utility (no options) doesn't behave as expected:

Here are the pertinent results:

/fpga/OAF/HD/rtl/vhdl_wrapper/clock_monitor_synthesis.v
/fpga/OAF/HD/rtl/vhdl_wrapper/clockmonitor_synthesis.v
/fpga/OAF/HD/rtl/vhdl_wrapper/clock_monitor_synthesis.v IN
/fpga/OAF/HD/rtl/vhdl_wrapper/clockmonitor_synthesis.v IN

Thanks for the report.  However, I fail to see that this is a bug.

This looks reasonable if you are using a locale that discards
punctuation from collation sorting (such as many implementations of
en_US.UTF-8).  This is a FAQ:
http://www.gnu.org/software/coreutils/faq/#Sort-does-not-sort-in-normal-order_0021

Try 'LC_ALL=C sort' on the same data, to force all bytes to behave in
ASCII ordering.  I'm marking this bug as closed for now, but if you can
provide compelling evidence that there really is a bug in sort after you
sort out your locale, then we can re-open it.  You may also want to try
the 'sort --debug' option in the latest coreutils 8.10 to help diagnose
what sort is really doing, and why it is correct (even if it is not what
you were wanting, because you didn't use the right command line options
and locale environment variables).
