Just as `math "bitand(5,3)"` and `math "bitor(6,2)"`.
These cast to long long before doing their thing,
so they truncate to an integer, producing weird results with floats.
That's to be expected because float representation is *very*
different, and performing bitwise operations on floats feels quite useless.
Fixes#7281.
Was: "parameter expansion takes before expressions are evaluated."
Now: "parameter expansion happens before expressions are evaluated."
I suspect the original intent was to use "takes place," but I see "happens" as less idiomatic and therefore may benefit non-English-native users.
Also return the number of failed files.
I decided to *just* print the filenames (newline-separated because
NULLs are annoying here) to make it easier to deal with.
See #7251.
This can be used to determine whether the previous command produced a real status, or just carried over the status from the command before it. Backgrounded commands and variable assignments will not increment status_generation, all other commands will.
There are a few code blocks where the default highlighting does not
work and the documentation looks bad as a result. Usually this happens
when we are demonstrating an important interactive feature, such as
autosuggestions, syntax highlighting, or tab completion.
The pygments highlighter was not designed for code samples like these.
But it is important to show the behavior clearly in the docs. I am
attempting to make these weird examples look as much like the "normal"
code blocks as possible.

One of the nicest things about fish is how introspectable it is. We
should probably get people to just mess around and see what is
implemented how. This is a step in that direction.
[ci skip]
- add missing links for some commands (control flow section)
- fix broken links that use the old syntax (#tut_ links)
- miscellaneous fixing of backticks/emphasis
This was always awkward as fish script, and had problems with
interrupting the autoloading.
Note that we still leave the old function intact to facilitate easier
upgrading for now.
Fixes#7145.
Add a helper function to check if the user is root. This function can be
useful for the prompts for example. Modify the prompts made root checked
to use the function instead. Add also the support of Administrator like
a root user.
Fixes: #7031
