Those are round braces, not curly braces, and they create a sub-shell. Right now their only side-effect is wasting time and memory, but if you make a habit of that you'll discover that variable assignments and the like don't communicate outside them.

So they're not decorations and can cause problems if you make a habit of it.

NAME
ecppl - language-extractor for ecpp SYNOPSIS
ecppl [-I dir] [-ln] [-o output-filename] ecpp-filename DESCRIPTION
Ecppl is the language-extractor for ecpp. Ecpp - the template-language used with tntnet - supports internationalized applications. In ecpp-templates a tag <i18n> changes the meaning of curly braces. A phrase, which is enclosed in curly braces, can be translated. At run- time the phrase is looked up in a language-library. This mode can be quit with the tag </i18n>. Phrases must not have newlines or tabs. Every phrase, which is marked as translatable, is extracted with ecppl and written to standard output or to a specified output-filename line by line. OPTIONS
-I dir Search include-files in directory. This option can be passed multiple times. All specified directories are searched in turn for include-files. -l Extract language-phrases (the default) -n Extract non-language-phrases -o filename Specify output filename AUTHOR
