hgweb: add less/more links for search logs (issue1972)

hgweb: add less/more links to shortlog/filelog nav

hgweb: make graph page size equal to shortlog

merge with stable

ui: just return it if it's already a bool

demandimport: ignore _winreg (used in python-2.7 mimetypes)

shrink-revlog: add --dry-run option

cmdutil: hide child window created by win32 spawndetached() Hiding the child process window is not strictly necessary but it avoids opening an empty shell window when running hg serve as well as a task in the task bar. The window is hidden after the process is already started causing a single flicker.

Find right hg command for detached process On Windows, Mercurial can be run from the python script of from a frozen executable. In the first case, we have to call the python interpreter since the script is not executable. Frozen executable can be called directly. Fix 3/3 for issue421

cmdutil: replace unix pipe handshake with file lock The pipe handshake cannot be implemented with Windows detached process, which disables handle inheritance. Fix 2/3 for issue421

serve: add and use portable spawnvp replacement There is no standard python command to really detach a process under Windows. Instead we use the low level API wrapped by subprocess module with all necessary options to avoid any kind of context inheritance. Unfortunately, this version still opens a new window for the child process. The following have been tried: - os.spawnv(os.P_NOWAIT): works but the child process is killed when parent console terminates. - os.spawnv(os.P_DETACH): works on python25, hang on python26 when writing to the hgweb output socket. - subprocess.CreateProcess() hack without shell mode: similar to os.spawnv(os.P_DETACH). Fix 1/3 for issue421

shrink-revlog: help/doc tweaks - make it look right in 'hg help extensions' - clarify --revlog option - add a main program to tell users this is no longer a standalone script

Add shrink-revlog.py to win32 installer

shrink-revlog: make it work on windows (issue1976)

shrink-revlog: avoid cryptic error when used as an extension When shrink-revlog is used as an extension, it would produce an error when switching back to stable because the script will try to execute itself.

transaction: initialize self.journal to None after deletion This avoid a warning when having an empty transaction, where hg would try to delete the journal twice.

subrepo: fix typo in help text

Merge with stable

relink: ensure consistent candidate order

commands: fix typo in help text

win32: close file when leaving _getfileinfo()
