tests: avoid nested quoting on command line for portability
Before this patch, test-revset.t fails on Solaris using ksh as default
"sh", because nested quoting below isn't acceptable for it.
+-----------------------------+ inner quoting
"`python -c "print '|'.join(['0:1'] * 500)"`"
+-------------------------------------------+ outer quoting
This patch does below for portability.
- omit outer quoting
This should be safe, because generated string contains no white
space character.
- use '+' instead of '|' (for safety)
'|' has special meaning for many shell, but '+' isn't (at least,
for ordinary ones).
