Running the tests on travis revealed that some compilers (or at least
with some options) call the wrong struct constructor if there is more
than one struct with the same name but differing definitions.
Hoist the code for parsing flags out of each individual subcommand and
into a function shared by all the subcommands. This reduces duplication
and potential for error. More importantly it makes the code that
actually implements the subcommand more prominent.
The Haiku stdio library has a bug. If we set stdout to unbuffered and it
is attached to a tty it discards wide output. Given how we interact with
the tty it should be safe to replace the problematic `fputwc()` calls
with simple `write()` calls. This does depend on the rest of the fish
code that writes to the tty to ultimately call write() which is true at
this time and should remain true in the future.

This came up in the context of issue #4068. This change makes it more
likely that the correct translation from english to another language
will be done for the "Job ... has {ended,stopped}" message.
The problem was overlooking a `break` statement when refactoring a
`switch` block into a simpler `if...else...` block. This fixes the
behavior of the `history-token-search-backward` function and its forward
searching analog.
Fixes#4065
This started out as a refactoring to eliminate the lint warnings. Adding
unit tests revealed the current implementation does not behave as
implied. So this is a complete rewrite of the implementation. With the
addition of unit tests so that it doesn't break in the future and anyone
who thinks this new version behaves wrong can update the unit tests to
help ensure we're testing for the correct behavior.
Fixes#4027
Some platforms do not correctly define `struct dirent` so that its
`d_name` member is long enough for the longest file name. Work around
such broken definitions.
Fixes#4030
The LRU cache wants to store references from nodes back into the
lookup map, so that it is efficient to remove a node from the
map. However certain compilers refuse to form a std::map::iterator
with an incomplete type. Fix this by storing a pointer to the key
instead of the iterator.
