- "1.6.0" now supports formatting let-else statements which we use liberally,
and appears to have some fixes in regards to long-indented-lines with macros
like `wgettext_ft!`
- This commit updates the formatting so that devs with the latest stable don't
see random format-fixes upon running `cargo fmt`
This ports some signal setup and handling bits to Rust.
The signal handling machinery requires walking over the list of known signals;
that's not supported by the Signal type. Rather than duplicate the list of
signals yet again, switch back to a table, as we had in C++.
This also adds two further pieces which were neglected by the Signal struct:
1. Localize signal descriptions
2. Support for integers as the signal name
Prior to this change, wstr::split had two weird behaviors:
1. Splitting an empty string would yield nothing, rather than an empty
string.
2. Splitting a string with the separator character as last character
would not yield an empty string.
For example L!("x:y:").split(':') would return ["x", "y"] instead of
what it does in C++, which is ["x", "y", ""].
Fix these.
fish_wcstoi_partial is like fish_wcstoi: it converts from a string to an
int optionally inferring the radix. fish_wcstoi_partial also returns the
number of characters consumed.
