as per the coding style guide:
https://projects.gentoo.org/qa/policy-guide/ebuild-format.html#pg0101
if it previously used [ ${PV} ... ] it uses [[ ${PV} ... ]] now
if it previously used [[ ${PV} = b ]] or [ ${PV} = b ], it uses
[[ ${PV} == b ]] now
the changes were generated using these two commands:
```
find -name '*.ebuild' -exec sed -i -E \
's|([^[])\[+(\s+)(\S*\$\S*PV\S*)(\s+)(\S+)(\s+)(\S+)(\s+)\]+([^]])|\1\[\[\2\3\4\5\6\7\8\]\]\9|g' \
{} \+
find -name '*.ebuild' -exec sed -i -E \
's|\[(\s+)(\S*\$\S*PV\S*)(\s+)==?(\s+)(\S+)(\s+)\]|\[\1\2\3==\4\5\6\]|g' \
{} \+
```
this is aimed to be a series of commits meant to replace all instance of
POSIX [ ... ] to bash's [[ ... ]], to make guru up to date with the
coding style guide
this process is divided up into a series of commits in order to make
review and testing more easy
