Benno Schulenberg 4af1da7d95 color: push the resets further when start and end match are equal
When for a multiline syntax-coloring rule the starting regex matches at
the exact same spot as the ending regex, do a second round of resets, so
that reevaluation starts further back and gets a few more things right.

This mildly fixes https://savannah.gnu.org/bugs/?47420.

Benno Schulenberg 528b79b5f3 tweaks: rename a variable to be more accurate
When we get a ^J as verbatim input, it is not possible to include it
into the file buffer or the prompt answer, because this would mean
adding an encoded null to the buffer or answer, and that is not what
the user intended.  One option would have been to simply ignore a ^J
in verbatim input.  But the choice has been made to act the same way
as when the ^J (0x0A) is found in the file data: start a new line.

That is the same response as to the Enter key, yes -- but the code
for the Enter key is ^M (0x0D), not ^J.  So, to be more precise,
rename the relevant variable from 'got_enter' to 'got_newline'.

Rishabh Dave 4957c1121d browser: select an inaccessible directory also when tabbed
When the user tab-completed a name at the Go To Directory prompt, this
name will end in a slash.  Remove this slash, so the name can be found
in the file list (where directory names don't include the final slash).

This fixes http://savannah.gnu.org/bugs/?48353.

Benno Schulenberg 8686cb3d3d chars: measure invalid sequences and unassigned codepoints more quickly
Invalid multibyte sequences get depicted with the Replacement Character,

Benno Schulenberg 91fff2a2c8 screen: avoid looking up the width of whitespace and control codes

Benno Schulenberg cf0eed6c36 screen: don't check for every character whether there is still enough space
Just allocate ample space up front and thus discard the delaying 'if' for
each and every character.  In most cases this will allocate far too much,
but that hardly matters: it is freed again as soon as the line is printed.

Benno Schulenberg 03586c60da chars: represent the high-bit controls more intelligibly
Instead of showing the upper control codes like this:

   ^À ^Á ^Â ^Ã ^Ä ^Å ^Æ ^Ç ^È ^É ^Ê ^Ë ^Ì ^Í ^Î ^Ï
   ^Ð ^Ñ ^Ò ^Ó ^Ô ^Õ ^Ö ^× ^Ø ^Ù ^Ú ^Û ^Ü ^Ý ^Þ ^ß

show them like this:

   ^` ^a ^b ^c ^d ^e ^f ^g ^h ^i ^j ^k ^l ^m ^n ^o
   ^p ^q ^r ^s ^t ^u ^v ^w ^x ^y ^z ^{ ^| ^} ^~ ^=

The lower control codes continue to be shown like this:

   ^@ ^A ^B ^C ^D ^E ^F ^G ^H ^I ^J ^K ^L ^M ^N ^O
   ^P ^Q ^R ^S ^T ^U ^V ^W ^X ^Y ^Z ^[ ^\ ^] ^^ ^_

The representation of DEL (0x7F) continues as ^?.

Further, use knowledge of UTF-8 to avoid a roundtrip through
wide characters.

Benno Schulenberg ddd9c7a022 tweaks: try to distinguish between keystrokes and characters
Keystrokes are single integers (aided by the flags meta_key and
func_key) but in the input stream they can be encoded as escape
sequences (a series of bytes).  Characters are values in byte
range, but in UTF-8 one character can consist of multiple bytes.

Also rename two variables, because the secondary input buffer
that they refer to contains only characters (mostly just one),
never any shortcuts; and there are too many "kbinput" already.
