import: use "getcommiteditor()" instead of explicit editor choice This patch also enhances "test-import-bypass.t" and "test-import.t", because "hg import" hasn't been explicitly tested around editor invocation and "--edit" option. This patch explicitly tests below: - with "--bypass" (regardless of "--edit"): - not invoked, if the patch contains the commit message - not invoked, if the commit message is explicitly specified - invoked, otherwise (just adding comment) - without "--bypass": - with "--edit": - not invoked, if "--no-commit" is not specified - invoked, otherwise - without "--edit": - not invoked, if the patch contains the commit message - not invoked, if "--message" or "--logfile" is specified (just adding comment) - invoked, otherwise

graft: use "getcommiteditor()" instead of explicit editor choice This patch also enhances "test-graft.t", because "hg graft" hasn't been explicitly tested around editor invocation and "--edit" option.

amend: use "getcommiteditor()" instead of explicit editor choice This patch doesn't change any tests like as preceding patches, because editor invocation is already tested in "test-commit-amend.t".

commit: use "getcommiteditor()" instead of explicit editor choice This patch also eliminates "forceeditor" no more referred. This patch doesn't change any tests like as preceding patches, because editor invocation is already tested well.

backout: use "getcommiteditor()" instead of explicit editor choice This patch also enhances "test-backout.t", because "hg backout" hasn't been explicitly tested around editor invocation and '--edit' option.

backout: avoid redundant message examination Before this patch, "hg backout" examines "--message" and "--logfile" options explicitly. But this examination is redundant, because "commitfunc()" can receive the result of same examination by "cmdutil.logmessage()" in "cmdutil.commit()" through "message" argument. This patch avoids redundant message examination by "message" examination in "commitfunc()".

transplant: use "getcommiteditor()" instead of explicit editor choice This patch also enhances "test-transplant.t", because "hg transplant" hasn't been explicitly tested around editor invocation and "--edit" option.
