The main reason for this is that then these commands can have
the same bindings in VC-Dir buffers that they have under
vc-prefix-map. 'T' is a good mnemonic for "Topic" and a

Previously, 'quit' could cause remote endpoints to never get a
reply and thus sometimes hang. Ensure we always reply. Also,
give the application a chance to signal jsonrpc-error with the
served code=32000, meaning "no error".
* doc/lispref/text.texi (JSONRPC Overview): Rework section on
request dispatchers.
* lisp/jsonrpc.el (jsonrpc-connection-receive): Rework.
The info returned from `garbage-collect` is really handy to
track the evolution of the heap size, but sadly it's available only
at the cost of running a full GC, which has two big downsides:
it's slow, it affects what we're measuring, and it can't be used
in `post-gc-hook`.
So, this patch makes it available without running the GC.
* src/alloc.c (Fgarbage_collect_heapsize): New function, extracted from
`Fgarbage_collect`.
(Fgarbage_collect): Use it.
(syms_of_alloc): defsubr it.
* doc/lispref/internals.texi (Garbage Collection): Extract
documentation for it from that of `garbage-collect`.
* doc/lispref/internals.texi (Module Values, C Integer Types):
Mention that the example assumes Emacs was built with the
GMP library, not with mini-gmp. Mention stdckdint.h for
integer overflow checking, and mention Emacs integers
for values outside machine range.
Previously, if 'calc-string-maximum-character' wasn't a valid
character 'math-vector-is-string' would throw an error in the
comparison, leading to an incomplete display of the stack and a
cryptic error message. Instead, have 'math-vector-is-string'
return nil, which effectively disables the display of strings.
Refines feature introduced in bug#78528.
* doc/misc/calc.texi (Customizing Calc): Update description of
behavior for invalid 'calc-string-maximum-character'.
* lisp/calc/calccomp.el (math-vector-is-string): Return nil when

and simplify tests.

Remove trailing period from chapter and section titles.

support.

commit of 2019-05-17 "Clean up and simplify image-type setup". Fix
some commentary.

frame parameter (bug#80191); this continues from commit of
