tests: make test-simplemerge use absolute_import

crecord: cleanup the remains of commit confirmation The confirmation screen is now only used for the 'review' option we simplify the code and rename the function.

crecord: drop the extra confirmation screen The commit confirmation is not very useful -- it gives no way to view what you have selected, so you're blindly choosing whether to proceed or not, and it adds a lot of unnecessary friction to committing. In addition, we now have a working 'review' choice for those who really want to review the final change. Ryan McElroy initially submitted a config option to make this optional, but we never saw a V2. However as the freeze is near and curses have never been officially out of the door, I think it is worth skipping the config and trying getting it right for this release.

update: resurrect bare update from null parent to tip-most branch head The situation is tricky if repository has no "default" branch, because "null" revision belongs to non-existent "default" branch. Before e1dd0de26557, bare update from null would bring us to the tip-most non-closed branch head. e1dd0de26557 removed the special handling of missing "default" branch since we wanted to stick to the uncommitted branch in that case. But, if the parent is "null" revision, and if the missing branch is "default", it shouldn't be an uncommitted branch. In this case, bare update should bring us to the tip-most head as before. This should fix the test breakage introduced by e1dd0de26557.

tests: run import-checker with tests .t files

import-checker: parse python code from .t files

import-checker: track filenames for SyntaxErrors

import-checker: track SyntaxErrors We don't really need to report SyntaxErrors, since in theory docchecker or a test will catch them, but they happen, and we can't just have the code crash, so for now, we're reporting them.

import-checker: refactor source reading This will allow .t files to generate multiple sources. It will also allow .py doctests to generate additional sources.

tests: make test-pathencode use print_function
