[Message part 1 (text/plain, inline)]

Parindent (paragraph-indent-text-mode) doesn't work as described in help.
After starting a paragraph with spaces and adding a newline (return) after
the first line removes the spaces added at the beginning.
Also, cannot start a new paragraph with tab in Parindent.
M-q mushes all paragraphs not separated by blank lines together.
This happens in Emacs 24.5 and 25.1.1 (On Debian 9 and Windows).
I tried Emacs 22.3 on Windows and it doesn't have this problem.


Thanks,
Saideep

Yeah, this can be avoided by turning off electric-indent-mode.

It's because the indent-line-function is set to indent-to-left-margin.
Doing C-q TAB works.

Setting indent-line-function to a smarter function would fix this and
the newline problem.

I'm not able to reproduce this problem though.  As long the paragraphs
start with whitespace M-q doesn't combine them, as documented.  For
example, with the following buffer contents, pressing M-q doesn't change
the buffer:

   xxx xxxxxxxx xxxxx xxxxxx xxxxx xxx xxxxx xxx xxxxxxx xxx xxx xxx
xx xxxx x
   xxxx xxx xxxx xx xx xx xxxxxxx xxxx xxxxxxx xxx xxx xxx xx xxxx
xxxxx xx
