The goal is to catch cases where the return value exists, but is
forgotten. There was a large enough number of them to turn this
into a real check. Initially, I just wanted to implement it to fix
the problems, then delete the code. But since this is so common, I
think it is worth the annoyance.
It might not be the most pretty of change, but it works. With this
change, it is possible to have multiple "things" in the "same"
section having the "same" name.
This allows for C/C++ style functions with the same name but different
signatures. Lua doesn't handle this well, so it should usually be
avoided. However, constructors might be a valid exception. Most older
widget (and object) constructors have multiple random argument while
newer one use `args`. Deprecating the old ones for the sake of
standardization might be a bit too much for users upgrading from v3.5.
Given the only reason all of those deprecation would happen is because
"its pretty that way", then lets allow 2 constructors and avoid outrage.
* Move table functions out of awful.util into new gears.table
* travis: Use v9999 prefix for full requests
Make sure no newly deprecated functions are used
* Move all `awful.util.table.*` calls to `gears.table.*` calls
Move table test functions from awful/util_spec to new gears/table_spec
Change awful.util.subsets call to gears.math.subsets in awful/key.lua
It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.
