Benno Schulenberg 9021725d53 justification: limit the amount of recursion to prevent a stack overflow 2018-05-27 16:09:53 +02:00
Benno Schulenberg d00ab406bc wrapping: when autoindenting, use indentation of next line as example
When doing autoindentation, and the next line is not the start of
a new paragraph, then use the indentation of that line for the new
line, as it is more likely to have the desired indentation -- the
current line might be the start of the paragraph and thus could
have a deviant indentation.

Benno Schulenberg 432a7d7729 justification: find the beginning of a paragraph in a better way
Any line whose indentation differs from that of a pair of adjacent lines
is the beginning of a paragraph, also when its indentation is smaller.

This fulfills https://savannah.gnu.org/bugs/?53932,
and fixes point 2) of https://savannah.gnu.org/bugs/?53933.

Benno Schulenberg d7fe5a7db3 justification: recognize indented paragraphs also without --autoindent
Pico does not require any option to do this, so nano should neither.

Benno Schulenberg a832f33291 justification: when leading whitespace exceeds fill width, wrap anyway
Pico wraps at the last blank character before or on the target column;
if there is no such blank, then it will wrap at the first blank *after*
the target column -- when it can wrap, it will wrap.  Nano should do
the same (and judging from the comments, it intended to do the same),
instead of turning the paragraph into a single unwrapped line.

When executing a command in the current buffer and piping this buffer
(or marked region) to that command, then the cutting of the existing

Marco Diego Aurélio Mesquita f304b9aee1 new feature: allow piping (selected) text to an external command
When executing a command, it is now possible to pipe the entire buffer

The output from the command replaces the buffer (or the marked region),
or goes to a new buffer.

This fulfills https://savannah.gnu.org/bugs/?28993,

Benno Schulenberg 9bf57e5ca0 tweaks: do not needlessly renumber the lines in the buffer
For cuts, pastes, and inserts, the lines have already been renumbered;

Only when lines get split (ENTER) or fused together (JOIN) do the later
lines need to be renumbered.  This mirrors what is done for do_redo().

Benno Schulenberg f9103a5cb5 tweaks: make the fsfromline() call only for the undo types that need it

it is entirely superfluous.  Rearrange the undo types to make checking

Benno Schulenberg dd9766c2e0 editing: when --smooth is used, make <Enter>-at-bottom scroll one row
When using --smooth or 'set smooth', the screen should scroll the
minimum amount needed to get the cursor back into view.  (The only
exceptions are search, undo, and redo -- when there the cursor goes
offscreen, the cursor line is centered.)

This change brings the behavior of pressing <Enter> on the bottom
row into line with, for example, pasting a single line.  See also
