[Darshan-users] darshan-job-summary.pl fails with path containing underscores

[Phil Carns]

Oh, I see the issue now.  Your original explanation was perfect.   The 
underscore must appear in the mount point itself, rather than in the 
file name or in another subdirectory in the path.

The mount point name by itself is  displayed in the "Data Transfer Per 
Filesystem" table and we are not encoding the string properly in that case.

Thank you very much for the bug report.  This will be fixed in Darshan 
2.2.2.
