\b \? \+ \| are GNU extensions to sed
In BRE (Basic Regular Expressions) there is no \? \+ or \|
In ERE (Extended Regular Expressions) there is ? + and |
To specify sed to use ERE, specify the -E flag.
GNU grep does not distinguish between BRE and ERE, but other
implementations do. To make grep use ERE instead of BRE, specify
the -E flag.
The GNU extension \b has no equivalent in either BRE or ERE.
So, in line number 216, I used the whole initial expected output.
For quick reference (n/a means 'not available') -
GNU BRE | POSIX BRE | POSIX ERE
-------------------------------
\( | \( | (
\) | \) | )
\? | \{0,1\} | ? or {0,1}
\+ | \{1,\} | + or {1,}
\| | n/a | |
\b | n/a | n/a
Two problems:
1) the regex used to match the wid in the window tree can match the wid
appearing in window titles as well.
2) instead of picking the parent window of the target window to set
transparency, a random window which is listed just below the target
window will be chosen. not sure why was there a + 1.

leftovers:
1) config file path. Has to implement compatibility functionalities before
we can change it.
2) links in man pages. Has to migrate the repo first.
3) _COMPTON_SHADOW, it has become a defacto standard, so we have to keep
supporting it.
4) dbus names, undecided whether we should/could change it.
