So maybe instead of : cd "$srcdir/$pkgname-$pkgver" we could use : cd ${srcdir}/$pkgname-$pkgver ?
that would be totally illogical. the point of using ${foo} instead of $foo is that in some cases you really need ${foo}:
source=($pkgname_$pkgver) won't work, but source=(${pkgname}_$pkgver) will. (just an example but probably you got the point). because of this, some projects (like gentoo) force the usage of ${foo} everywhere.
this is not related to spaces, to deal with them, you always need quotes.
I already said it was stupid, but it is also illogical if you like :) I was just confused. And the fact that it worked with zsh, which is my primary shell, confused me even more. After Travis answer, I remembered it was probably just for separating the variable names. But thanks for confirming this is indeed the main reason.
