Wt

Hello!

This template text does not work (produces empty output):

<message id="KeyValue">
     ${tr:{1}}: ${{1}}
</message>

<message id="x.y.template.z">
    ${block:KeyValue x.a.obj.Name}
    ${block:KeyValue x.a.Description}
</message>

While this does work:

<message id="KeyValue">
     ${tr:{1}}: ${{1}}
</message>

<message id="x.y.template.z">
    ${block:KeyValue x_a_obj_Name}
    ${block:KeyValue x_a_Description}
</message>

('.' was replaced with '_' in arguments of block).

As well as this:

<message id="KeyValue">
     ${tr:{1}}: ${{1}}
</message>

<message id="x.y.template.z">
    ${block:KeyValue 'x.a.obj.Name'}
    ${block:KeyValue 'x.a.Description'}
</message>

It seems to be connected with argument parsing function parseArgs():

https://github.com/kdeforche/wt/blob/11eac89281216ad26e/src/Wt/WTemplate.C#L556

https://github.com/kdeforche/wt/blob/11eac89281216ad26e/src/Wt/WTemplate.C#L581

At L556, only '' is allowed, at L581 '' and '-', but not '.'

Allowed characters are not listed in description of WTemplate.
