demandimportpy3: only use lazy extension loader on Python 3.6+
There was an inline comment denoting a bug in the lazy extension
loader on Python 3.5 which prevents it from working there. But the
code was not conditional on the Python version.
The result of this was a myriad of failures on Python 3.5 due to
getattr() and friends not working on lazy extension modules.
By making extension modules non-lazy on Python 3.5, we reduce the
number of test failures from 48 to 22 on that Python version.

Most Mercurial commands accept various flags. Flag names ========== Flags for each command are listed in :hg:`help` for that command. Additionally, some flags, such as --repository, are global and can be used with any command - those are seen in :hg:`help -v`, and can be specified before or after the command. Every flag has at least a long name, such as --repository. Some flags may also have a short one-letter name, such as the equivalent -R. Using the short or long name is equivalent and has the same effect. Flags that have a short name can also be bundled together - for instance, to specify both --edit (short -e) and --interactive (short -i), one could use:: hg commit -ei If any of the bundled flags takes a value (i.e. is not a boolean), it must be last, followed by the value:: hg commit -im 'Message' Flag types ========== Mercurial command-line flags can be strings, numbers, booleans, or lists of strings. Specifying flag values ====================== The following syntaxes are allowed, assuming a flag 'flagname' with short name 'f':: --flagname=foo --flagname foo -f foo -ffoo This syntax applies to all non-boolean flags (strings, numbers or lists). Specifying boolean flags ======================== Boolean flags do not take a value parameter. To specify a boolean, use the flag name to set it to true, or the same name prefixed with 'no-' to set it to false:: hg commit --interactive hg commit --no-interactive Specifying list flags ===================== List flags take multiple values. To specify them, pass the flag multiple times:: hg files --include mercurial --include tests Setting flag defaults ===================== In order to set a default value for a flag in an hgrc file, it is recommended to use aliases:: [alias] commit = commit --interactive For more information on hgrc files, see :hg:`help config`. Overriding flags on the command line ==================================== If the same non-list flag is specified multiple times on the command line, the latest specification is used:: hg commit -m "Ignored value" -m "Used value" This includes the use of aliases - e.g., if one has:: [alias] committemp = commit -m "Ignored value" then the following command will override that -m:: hg committemp -m "Used value" Overriding flag defaults ======================== Every flag has a default value, and you may also set your own defaults in hgrc as described above. Except for list flags, defaults can be overridden on the command line simply by specifying the flag in that location. Hidden flags ============ Some flags are not shown in a command's help by default - specifically, those that are deemed to be experimental, deprecated or advanced. To show all flags, add the --verbose flag for the help command:: hg help --verbose commit
