New session not expanding \W in bash prompt correctly #1413
Description
Problem description
When I create a new session in Termux, the bash prompt ($PS1) doesn't expand \W as expected.
Steps to reproduce
Setup:
# ~/.bashrc
export PS1='\W$ 'Initial session:
~$ pwd && echo $PWD
/data/data/com.termux/files/home
/data/data/com.termux/files/home
~$ mkdir -p test/dir
~$ cd test/dir
dir$ pwd && echo $PWD
/data/data/com.termux/files/home/test/dir
/data/data/com.termux/files/home/test/dir
dir$ In a new session:
$ pwd && echo $PWD
/data/data/com.termux/files/home/test/dir
/data/data/com.termux/files/home/test/dir/
$ Expected behavior
Opening a new session shouldn't mangle the prompt. It seems the \W escape character isn't expecting a trailing slash in $PWD.
