This commit refactors `splits/2` implementation using `foreach` syntax
and reduces intermediate arrays. This refactoring removes an unnecessary
private (and undocumented) filter `_nwise` and closes#3148.
The introduction says all the usage examples (e.g. of truncate_stream,
etc) in the section use [0,[1]] as input, but they actually use [1,[2]].
["a",["b"]] seems better than [1,[2]] as the string values won't be
confusable with the indexes in <path>.
This comment predates the addition of $ARGS in jq 1.6, so there was no
way to access named arguments with an invalid identifier. Rather than
forbid such names, update the manual to clarify.
I also changed the behavior of limit/2 with negative count to emit an error, like nth/2 does.
Also, I redefined nth/2 using skip/2 to minimize the impact of growth of builtin filters.
* Fix typo in documentation for map_values
"map_value(f)" -> "map_values(f)"
* map_value => map_values also in the devolpment manual

This commit temporarily reverts the commit that allows #\ "tcl-style"
comments everywhere and documents them, for the 1.7.1 patch release
cca1f7d18f.
\r is removed from the list of characters not allowed in a comment to
preserve that bugfix.
The description of the Alternative operator `//` was hard for me to grasp in its wording.
I suggest dividing the looong sentence into two parts. Since it is actually an alternative formulation, the sentence can be divided into the first formulation, and the alternative formulation.
* bugfix: comments were incorrectly being terminated by CR; for example
jq -n $'1 #foo\r'
fails to compile because the CR character terminates the comment, and
CR is not a valid character in jq syntax.
* improvement: comments fully support Tcl-style line continuation.
Previously this was only "supported" in `-f' scripts, whose first line
starts with "#!", and second line starts with # and ends with \, only
for the comment on the second line, only for one extra line.
* man: document comment syntax, which was previously undocumented.
* tests: add regression tests for the bugfix, and some tests for line
continuation in comments.
jq previously only allowed passing the inline script before -- (as if
they were options) even though one would expect the inline script to be
a positional argument.
Since jq previously also refused to run with a usage error if the script
was passed after -- (It was not assuming . as script as it does when
no arguments are passed), and positional arguments are allowed before --
and even before other options, it should not be a breaking change to
change that weird behaviour, and allow the script to appear after --.
It also simplifies the option parsing code a bunch.
Fixes#2918
This patch removes the weird behaviour of jv_invalid_with_msg(jv_null())
that returns jv_invalid() (i.e. empty), instead of a boxed jv_null().
The previous behaviour of null|error was obviously unintentional, and
allowing is jv_invalid_with_msg() to return values on which you can't
call jv_invalid_get_msg() is only error prone.
