[PATCH 0/4] improve one-shot variable detection with shell function

[Eric Sunshine <ericsunshine@xxxxxxxxxxx>]

From: Eric Sunshine <sunshine@xxxxxxxxxxxxxx>

This series addresses a blind-spot of check-non-portable-shell's
detection of one-shot environment variable assignment with shell
functions. In particular, although it correctly detects:

    VAR=val shell-func

it will miss invocations such as:

    echo X | VAR=val shell-func
