templates: add filter to reverse list
The filter supports only lists because for lists, it’s straightforward to
implement. Reversing text doesn’t seem very useful and is hard to implement.
Reversing the bytes would break multi-bytes encodings. Reversing the code
points would break characters consisting of multiple code points. Reversing
graphemes is non-trivial without using a library not included in the standard
library.

'''manage a stack of patches
This extension lets you work with a stack of patches in a Mercurial
repository. It manages two stacks of patches - all known patches, and
applied patches (subset of known patches).
Known patches are represented as patch files in the .hg/patches
directory. Applied patches are both patch files and changesets.
Common tasks (use :hg:`help COMMAND` for more details)::
create new patch qnew
import existing patch qimport
print patch series qseries
print applied patches qapplied
add known patch to applied stack qpush
remove patch from applied stack qpop
refresh contents of top applied patch qrefresh
By default, mq will automatically use git patches when required to
avoid losing file mode changes, copy records, binary files or empty
files creations or deletions. This behavior can be configured with::
[mq]
git = auto/keep/yes/no
If set to 'keep', mq will obey the [diff] section configuration while
preserving existing git patches upon qrefresh. If set to 'yes' or
'no', mq will override the [diff] section and always generate git or
regular patches, possibly losing data in the second case.
It may be desirable for mq changesets to be kept in the secret phase (see
:hg:`help phases`), which can be enabled with the following setting::
[mq]
secret = True
You will by default be managing a patch queue named "patches". You can
create other, independent patch queues with the :hg:`qqueue` command.
If the working directory contains uncommitted files, qpush, qpop and
qgoto abort immediately. If -f/--force is used, the changes are
discarded. Setting::
[mq]
keepchanges = True
make them behave as if --keep-changes were passed, and non-conflicting
local changes will be tolerated and preserved. If incompatible options
such as -f/--force or --exact are passed, this setting is ignored.
This extension used to provide a strip command. This command now lives
in the strip extension.

selected guard, but will not be pushed if any negative guards
match the current guard. For example::
qguard foo.patch -- -stable (negative guard)
qguard bar.patch +stable (positive guard)
qselect stable
This activates the "stable" guard. mq will skip foo.patch (because
it has a negative match) but push bar.patch (because it has a
positive match).
With no arguments, prints the currently active guards.
With one argument, sets the active guard.
Use -n/--none to deactivate guards (no other arguments needed).
When no guards are active, patches with positive guards are
skipped and patches with negative guards are pushed.
qselect can change the guards on applied patches. It does not pop
guarded patches by default. Use --pop to pop back to the last
applied patch that is not guarded. Use --reapply (which implies
--pop) to push back to the current patch afterwards, but skip
guarded patches.
Use -s/--series to print a list of all guards in the series file
