Previously, there were a few places where the compiler would create
strings from template content and emit them as template literals, but
didn't properly escape characters or character sequences with special
meanings, in particular: backslashes, backticks, and interpolation
sigils.
This commit fixes this in:
- block creation (interpolation sigils were not escaped)
- text node creation (no escaping was performed)
- comment not creation (no escaping was performed)
- default values for t-esc (no escaping was performed)
- body of a t-set (no escaping was performed)
The problem was that the compiler is based on the assumption that the
multi block received by the parser only occurs in some cases
where the structure of the template require a multi block, and it does
not work when we have random multiblock elsewhere.
We could fix the issue by modifying the code generator code to support
these usecases, or by simply removing these cases in the parser. Since
this seems more efficient, this is the approach taken by this commit.
Note that it was a good opportunity to simplify the parser.
