/* Avoid running this transformation on the strempty function itself and
|
|
* on the "make_expression" macro in src/libsystemd/sd-bus/bus-convenience.c.
|
|
* As Coccinelle's Location object doesn't support macro "detection", use
|
|
* a pretty horrifying combo of specifying a file and a special "something_else"
|
|
* position element, which is, apparently, the default value of
|
|
* "current_element" before it's set (according to the source code), thus
|
|
* matching any "top level" position, including macros. Let's hope we never
|
|
* introduce a function called "something_else"...
