py3: handle opts correctly for rollback dryrun and force are just check for None, the value is not used. So its better to leave opts as unicodes as that wont harm us.

py3: handle opts correctly for unbundle There is just a check whether the value is None or not. So even having optupdate as unicodes won't harm us.

py3: convert opts to bytes in cmdutil.dorecord() commands.commit() calls cmdutil.dorecord() where opts are passed as unicodes being keyword arguments. This patch converts them back to bytes as they are required.

py3: make sure opts are passed and used correctly in help command opts are converted back to bytes in help.help_() where they are used. Before that it's ensured that we have a bytes value for keep variable.

py3: handle opts uniformly in commands.py Since keyword arguments can't be bytes on Python 3, we converted then to unicodes before passing into different command functions. We need to adopt a certain pattern to convert opts back to bytes. Following are some of the functions which are called from inside these command functions and should always be feeded bytes to follow the right behaviour. ui.fomattter() scmutil.match() patch.diffallopts() hg.peer() cmdutil.{show_changeset|copy|graphrevs|checkunsupportedflag} server.{createservice|runservice} There are few commands which are left out where opts is again passed to a function as keyword arguments or converting opts back to bytes is kind of not necessary. Those are cat, revert, help, unbundle and rollback. Following patches will deal with them. This patch apart from these five commands, convert opts back to bytes for rest of the commands. This fixes a lot of things which are hidden like --git works now. Similarly more flags of commands which run on Python 3 currently get fixed.

help: call out specific replacement configuration settings As an aside, I'm having trouble parsing the help text meaning for HG when it is unset or empty. How can it be the frozen name or searched if it is empty?

help: spelling fixes

help: attempt to clarify that pager usage is not output length based This may be too subtle of a change to get the point across, but when I first read the original text, I thought maybe the pager would only be invoked if writing more than a screenful. The distinction between this and a pager that simply exits after printing less than a screenful is important on Windows, given the inability of `more` to color output.

help: document color/pager pitfalls on Windows Even though I figured this out a few weeks ago, I was initially puzzled where the color went when I upgraded to 4.2 on a different Windows machine. Let's point users reading the help into the right direction. I wonder if we should be even more explicit about cmd.exe/MSYS/pager/color interplay, but at least all of the breadcrumbs are here (I think).
