test-ssh: stabilize for Windows Previously, this complained: remote: '.' is not recognized as an internal or external command, remote: operable program or batch file. Making this a python script apparently revealed some races[1]. Thanks to Yuya for suggesting this. [1] https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-December/109094.html

templater: register keywords to defaults table Since the keywords are permanent, there should be no need to pass them by a temporary mapping.

templater: drop unneeded resources from conflict-marker data Follow-up for 32c278eb876f and f1c54d003327.

templater: rewrite docstring of templater.__init__() More importantly, this patch adds what the cache is.

rebase: don't take out a dirstate guard for in-memory rebase Since IMM doesn't affect the dirstate, it's not needed, and might be faster. Differential Revision: https://phab.mercurial-scm.org/D1745

test-split: stabilize for Windows - $PYTHON needs to be quoted when used as an executable in $HGEDITOR. This avoids the error "'c' is not recognized as an internal or external command". - seq.py is printing out CRLF, and then the subsequent `sed` script seems to convert to LF on MSYS. IDK if python print statements can be made to print LF on Windows, and I'm pretty sure CRLF is baked into some other tests. - A stray glob was causing the 'obsstore-off' case to report 'no result code from test'. - When I ran with --debug, the `hg diff` commands in the test both printed color sequences, and paused the output as it was run through the pager.
