patch: better handling of sequence of offset patch hunks (issue1941) The built-in patch implementation applied the hunks to the wrong lines of the file if the file in the repo has been modified to skew the patch line numbers and the file contains repetitive sequences of lines.

Makefile: added instructions on how to override PREFIX

win32text: do not mention hgext in warning

patch: drop unused hunk.newctrl()

test-import-eol: improve binary hunks test

diffhelpers: handle CRLF in hunk last line without EOL Note that diff generation code always ends last lines without newline with a LF, so this is a tolerance.

patch: drop eol normalization fast-path for 'lf' and 'crlf' With eolmode set to 'lf' or 'crlf' we avoided the hunk duplication and normalization by reading the input patch in text mode. Dropping this optimization simplifies code expectations for a small overhead. The change in test-mq-eol comes from a tolerance to CRLF instead of LF for last lines without newlines being broken by this revision. This tolerance was only partially supported and will be added again in a better way.
