That looks like an invalid character in the command here (and those
below). I probably didn't notice it before and just fixed up my local
commands...

... but this suggests it's not being interpreted as a command flag.
E.g., a command with the wrong character:

# xfs_quota -x -c 'project –c task1' /mnt
–c - no such project in /etc/projects or invalid project number
Checking project task1 (path /mnt/task1)...
/mnt/task1 - project identifier is not set (inode=0, tree=11)
/mnt/task1 - project inheritance flag is not set
Processed 1 (/etc/projects and cmdline) paths for project task1 with recursion depth infinite (-1).

vs. with the correct:

# xfs_quota -x -c 'project -c task1' /mnt
Checking project task1 (path /mnt/task1)...
/mnt/task1 - project identifier is not set (inode=0, tree=11)
/mnt/task1 - project inheritance flag is not set
Processed 1 (/etc/projects and cmdline) paths for project task1 with recursion depth infinite (-1).

All in all, you should see something like the following from the '-s'
command before this is expected to work:

# xfs_quota -xc 'project -s task1' /mnt
Setting up project task1 (path /mnt/task1)...
Processed 1 (/etc/projects and cmdline) paths for project task1 with recursion depth infinite (-1).

And for further verification, the project ID should be set on the
associated directory:

# xfs_io -c "lsproj" /mnt/task1
projid = 11
