plovs reported a crash when templates were not installed properly,
with a non-useful error about the template object not being defined.
I've audited all uses of template_depends(), and template(), and it makes
sense for them to throw an error if the template cannot be found. All code
with a user-supplied template catches errors already, to handle template
parse failures.
It did not make sense for template_file to throw errors, as some code uses
it to probe if a template file is available.
The HTML::Tree changelog says:
[THINGS THAT MAY BREAK YOUR CODE OR TESTS]
...
* Attribute names are now validated in as_XML and invalid names will
cause an error.
and indeed the regression tests do get an error.
With a relative xrds-location, the openid perl client module will fail.
I haven't checked the specs to see if it needs to be absolute, but all
examples I've seen are absolute, so it seems a very good idea.
I also tried setting RPC::XML::ENCODING but that did not prevent the crash,
and it seems that blogspam.net doesn't like getting xml encoded in unicode,
since it mis-flagged comments as spammy that way that are normally allowed
through.
If I am not mistaking all source files in ikiwiki are encoded in Unicode UTF-8.
Adding `\usepackage[utf8]{inputenc}` enables LaTeX to deal with the encoding.
As a consequence some special characters like umlauts can be used in the source
code which is useful for foreign languages.
[[!teximg code="a = b \text{ für alle } b \neq 2"]]
But for example »≠« cannot be used in LaTeX right now. One has to use other TeX
systems like XeTeX or LuaTeX featuring native UTF-8 support or use additional
nonstandard packages like uniinput [1].
I used the package `inputenc` (`texdoc inputenc`) and not `inputenx` (`texdoc
inputenx`), because I have not used `inputenx` that much and using the option
`math` is not supported in Debian (and I guess other distributions too) since
`inpmath` is not included in CTAN.

Avoid the generic "you are not allowed to change" message,
and instead allow check_canedit to propigate out useful error messages.
Went back to calling check_canedit in fatal mode, but added a parameter to
avoid calling the troublesome subs that might cause a login attempt.
