Here, the user gave an argument name but failed to provide the required
parameters to the argument. Tell the user which argument wants more.
This is an API change that may affect programs trying to match the
specific "Too few arguments" message. The new error message appends the
user-supplied argument that caused the error.
A solution which works with both versions is to look for "Too few
arguments" at the beginning of the error message.
- if (err.what() == "Too few arguments")
+ if (std:string(err.what()).rfind("Too few arguments", 0) == 0)

While it's good to test around error conditions, the main purpose of this
test is to catch future changes in the error type and message.

Argument.scan handles simple string to numeric type conversions, removing
the need to create a lambda. Argument.action is still necessary for more
complex conversions and those are left unchanged.

This change also explicitly lists the source files
for CMake. This is because `GLOB` does not remove
old files when switching branches in Git, and
`CONFIGURE_DEPENDS` will add unstaged files after
stashing.
