doc: correct example concerning "hg purge" alias in man page "hgrc.5" The "hg purge" alias as currently described in "hgrc.5" only works, if the caller's current working directory is identical to the repository's root directory. This patch slightly modifies the example by adding an empty pattern as a file argument to the "hg status" command, thus forcing this command to list the affected files relative to the current directory.

fileset: fix copy/paste in eol() error message

run-tests: factor out _escapepath

debugignore: normalize the file before testing dirstate._ignore() With an ignore pattern containing a '/' and a Windows style path containing '\', status was properly ignoring the file, but debugignore was stating that it wasn't ignored.

check-code: add rule to detect usage of external diff via extdiff This rule detects "hg extdiff" invocation without -p/--program and -o/--option. This patch specifies "-p diff" explicitly in test-extdiff.t to avoid false positive matching.

tests: use portable diff script via extdiff extension Before this patch, some tests using external "diff" command via extdiff extension fail on Solaris, because of incompatibility of "diff" command and its output. For example, system standard "diff" (= /usr/bin/diff) on Solaris differs from GNU diff in points below: - "-N" (treat absent files as empty) option isn't supported - files are examined not in dictionary order (maybe, in order in storage) This patch introduces portable diff script "pdiff" and make tests use it via extdiff extension. For portability of tests, this patch invokes "pdiff" script with explicit "sh", because standard shell of runtime platform ("cmd.exe" on Windows) is used at first to invoke external diff command.
