vasilito facf0c92e0 feat: track all source trees in git — full fork offline-first model 
Red Bear OS is a full fork. All sources must be available from git clone
with zero network access. Removed gitignore rules that excluded fetched
source trees under recipes/*/source/, local/recipes/kde/*/source/,
local/recipes/qt/*/source/, and vendor source trees.

Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded.

127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt
frameworks, mesa, wayland, DRM drivers, and every other recipe source.

/* Java MessageFormat format strings are described in

See also the ICU documentation class_MessageFormat.html.
messageFormatPattern := string ( "{" messageFormatElement "}" string )*
messageFormatElement := argument { "," elementFormat }
elementFormat := "time" { "," datetimeStyle }
| "date" { "," datetimeStyle }
| "number" { "," numberStyle }
| "choice" { "," choiceStyle }
datetimeStyle := "short"
| "medium"
| "long"
| "full"
| dateFormatPattern
numberStyle := "currency"
| "percent"
| "integer"
| numberFormatPattern
choiceStyle := choiceFormatPattern
dateFormatPattern see SimpleDateFormat.applyPattern
numberFormatPattern see DecimalFormat.applyPattern
choiceFormatPattern see ChoiceFormat constructor
In strings, literal curly braces can be used if quoted between single
quotes. A real single quote is represented by ''.
If a pattern is used, then unquoted braces in the pattern, if any, must
match: that is, "ab {0} de" and "ab '}' de" are ok, but "ab {0'}' de" and
"ab } de" are not.
The argument is a number from 0 to 9, which corresponds to the arguments
presented in an array to be formatted.
It is ok to have unused arguments in the array.
Adding a dateFormatPattern / numberFormatPattern / choiceFormatPattern
to an elementFormat is equivalent to creating a SimpleDateFormat /
DecimalFormat / ChoiceFormat and use of setFormat. For example,
MessageFormat form =
new MessageFormat("The disk \"{1}\" contains {0,choice,0#no files|1#one file|2#{0,number} files}.");
is equivalent to
MessageFormat form = new MessageFormat("The disk \"{1}\" contains {0}.");
form.setFormat(1, // Number of {} occurrence in the string!
new ChoiceFormat(new double[] { 0, 1, 2 },
new String[] { "no files", "one file",
"{0,number} files" }));
Note: The behaviour of quotes inside a choiceFormatPattern is not clear.
Example 1:
"abc{1,choice,0#{1,number,00';'000}}def"
JDK 1.1.x: exception
JDK 1.3.x: behaves like "abc{1,choice,0#{1,number,00;000}}def"
Example 2:
"abc{1,choice,0#{1,number,00';'}}def"
JDK 1.1.x: interprets the semicolon as number suffix
JDK 1.3.x: behaves like "abc{1,choice,0#{1,number,00;}}def"
