templater: give better error message for invalid engine type Before, KeyError was caught at changeset_templater._show(), which said "no key named '%s'" as it was intended to catch the KeyError of unknown map key. Instead, we should catch KeyError explicitly for better error indication. For those who don't know what the template engine is (read "everyone"), it is hidden extension feature that allows switching template syntax in map file. See d8c5a7f25a40 for details.

When Mercurial accepts more than one revision, they may be specified
individually, or provided as a topologically continuous range,
separated by the ":" character.
The syntax of range notation is [BEGIN]:[END], where BEGIN and END are
revision identifiers. Both BEGIN and END are optional. If BEGIN is not
specified, it defaults to revision number 0. If END is not specified,
it defaults to the tip. The range ":" thus means "all revisions".
If BEGIN is greater than END, revisions are treated in reverse order.
A range acts as a closed interval. This means that a range of 3:5
gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
