add: introduce a warning message for non-portable filenames (issue2756) (BC)
On POSIX platforms, the 'add', 'addremove', 'copy' and 'rename' commands now
warn if a file has a name that can't be checked out on Windows.
Example:
$ hg add con.xml
warning: filename contains 'con', which is reserved on Windows: 'con.xml'
$ hg status
A con.xml
The file is added despite the warning.
The warning is ON by default. It can be suppressed by setting the config option
'portablefilenames' in section 'ui' to 'ignore' or 'false':
$ hg --config ui.portablefilenames=ignore add con.xml
$ hg sta
A con.xml
If ui.portablefilenames is set to 'abort', then the command is aborted:
$ hg --config ui.portablefilenames=abort add con.xml
abort: filename contains 'con', which is reserved on Windows: 'con.xml'
On Windows, the ui.portablefilenames config setting is irrelevant and the
command is always aborted if a problematic filename is found.
$ hg init
$ echo foo > foo
$ echo bar > bar
$ hg ci -qAm 'add foo bar'
$ echo foo2 >> foo
$ echo bleh > bar
$ hg ci -m 'change foo bar'
$ hg up -qC 0
$ hg mv foo foo1
$ echo foo1 > foo1
$ hg cat foo >> foo1
$ hg ci -m 'mv foo foo1'
created new head
$ hg merge
merging foo1 and foo to foo1

$ hg debugstate --nodates
n 0 -2 bar
m 644 14 foo1
copy: foo -> foo1
$ hg st -q
M bar
M foo1
Removing foo1 and bar:
$ cp foo1 F
$ cp bar B
$ hg rm -f foo1 bar
$ hg debugstate --nodates
r 0 -2 bar
r 0 -1 foo1
copy: foo -> foo1
$ hg st -qC
R bar
R foo1
Re-adding foo1 and bar:
$ cp F foo1
$ cp B bar
$ hg add -v foo1 bar
adding bar
adding foo1
$ hg debugstate --nodates
n 0 -2 bar
m 644 14 foo1
copy: foo -> foo1
$ hg st -qC
M bar
M foo1
foo
Reverting foo1 and bar:
$ hg revert -vr . foo1 bar
saving current version of bar as bar.orig
reverting bar
saving current version of foo1 as foo1.orig
reverting foo1
$ hg debugstate --nodates
n 0 -2 bar
m 644 14 foo1
copy: foo -> foo1
$ hg st -qC
M bar
M foo1
foo
$ hg diff
