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

Dear all,


I am experiencing a strange behaviour of eshell on emacs 26.2:


Steps to reproduce:

emacs -Q
M-x eshell
(setq pcomplete-ignore-case t)


Description:

Under some circumstances, completion of paths starting with "~" leads to 
"~" being expanded to the full path and overwriting the previous text.

Example: suppose I wanted to copy the directory 
~/Documents/some_directory/ to my ~/Downloads/ folder. I type

cp -r ~/doc<TAB>

and it correctly expands to

cp -r ~/Documents/

However, when I continue with

cp -r ~/Documents/my_directory ~/dow<TAB>

it expands to

cp -r ~/Docume/home/username/Downloads/


It seems related to this bug:
