23206	Placeholders in mapcss expressions don't work in suggestAlternative	Famlam	team	"==== What steps will reproduce the problem?
1. Have the following mapcss validation rule to demonstrate the issue
{{{#!mapcss
*[xxx=12345] {
  throwWarning: tr(""3 times same way to get yyy={0}"", get(regexp_match(""^12345$"", ""{0.value}""), 0));
  suggestAlternative: concat(""yyy="", get(regexp_match(""^12345$"", ""{0.value}""), 0));
  fixAdd: concat(""yyy="", get(regexp_match(""^12345$"", ""{0.value}""), 0));
}
}}}
2. Validate an element with tag `xxx=12345`
3. Notice that:
- The throwWarning text is `3 times same way to get yyy=12345` as expected
- The fixAdd autofix result is that tag `yyy=12345` is added as expected
- However, the suggestAlternative text reads `use yyy= instead` (instead of `use yyy=12345 instead`)

All three lines use the exact same mapcss code: `get(regexp_match(""^12345$"", ""{0.value}""), 0)`.

So it seems that the placeholders in function expressions (added in r18757) work as expected for `throw*` and `fix*` commands, but they don't seem to work for `suggestAlternative`.
